* A GOP ad against Senate candidate Harold Ford -- featuring a white seductress who says she met the black lawmaker at a Playboy party and that he should call her -- is so odious and racially tinged that Ford's Republican opponent, Bob Corker, denounces it.

* Republican Wyoming congresswoman Barbara Cubin tells a wheelchair-bound Libertarian candidate after a debate: "If you weren't sitting in that chair, I'd slap you in the face."

* Hillary Clinton's opponent says she used to be ugly -- and why did Bill marry her, anyway? -- but now looks okay thanks to millions in plastic surgery.
